HR and IM

Triathlon Forum

I am wondering what the ideal HR would be for the marathon at the end of IM (FL for me coming up). Is 150 bpm too high? and how much does heart rate differ from a normal marathon compared to a IM marathon (taking into account same conditions, good fuel intake, etc. Also what are peoples rate for the bike leg?

thanks

I don’t know if this is your first IM. I did my first IM on Sunday in Austria and I think that HR is totally irrelevant in the marathon, you just don’t have the power to get the HR that high.

For me it was an effort to keep running and finish strong, did it in 11:14:30 and the marathon in 4:15.
